JProbe is a servlet for inspecting running thread inside a servlet container and detect those gone haywire.

JProbe is designed to be a minimalisitc tool to list and inspect all threads running on the JVM. Packaged in a deployable web archive, JProbe can be deployed next to a running servlet and inspect this servlet's threads. This allows for finding threads that are stuck with a minimal impact on the running web applications.

JProbe can be build using Apache Ant. The build script is located in build.xml and can be configured in build.properties.

The minimum configuration required is setting the servlet-libs.location property to point to a folder containing the Java Servlet library (servlet-api.jar). This library is bundled with all Java Servlet implementions, e.g. Apache Tomcat.

A war (Web ARchive) file can be bundled by running: ant all

The default password is 's3cr3t' and should be set to a secure password in web.xml before deployment in a production environment.

JProbe is licensed under the terms of the Apache License version 2.0, see the included LICENSE file.
